How to make arbitrary POST requests using Zombie
var browser = new Browser();
browser.visit('/hello', function() {
// do some checks
// I'm not sure if browser.resources is an official part of the Zombie API (I found it by searching the src)
// so be wary in case it changes

basic support for PostgreSQL Enums in ActiveRecord - to be placed in an initializer
##
# This provides `create_enum` and `drop_enum` methods for migrations, which creates
# a Postgres ENUM type with the provided values.
#
# It'll also dump these into the schema.rb to be loaded into another DB (e.g. rake db:test:load)
#
# In order to reference the new enums as actual types, ActiveRecord needs to know about them, so
# make sure they are all represented in the `types` array below
#
# Then you can reference them in your migrations, e.g.

Support for PostgreSQL `interval` type in Rails 4. Although ActiveRecord supports `interval` by default, it turns it into a string (and tells Postgres the column is type string, too). This means you don't get any proper interval goodness. By sticking this code into an initialiser, ActiveRecord will create proper `interval` column types in Postgr…

# This will force ActiveRecord to create proper `interval` column types in PostgreSQL
#
# def change
# add_column :leases, :period, :interval
# end
#
# This applies to a generated `schema.rb` file too.
#
# No special OID type is applied to an `interval` type. Rails will treat it as a string, although

A Chef recipe for creating EBS volumes. See: http://clarkdave.net/2013/04/managing-ebs-volumes-with-chef/
# The database recipe should be included by any server running a DB. It creates
# a /data directory and, if on EC2, will mount an EBS volume here
directory '/data' do
mode '0755'
end
if node[:app][:ec2] || node[:cloud][:provider] == 'ec2'
